The position information acquisition unit 14 stores the travel route information including the acquired position information in a storage unit such as the RAM 103.

The in-vehicle device 10A repeats the processes of steps S101 and S102 while the vehicle A is driving. As a result, the in-vehicle device 10A performs vehicle-to-vehicle communication with a large number of other vehicle B in-vehicle devices 10B that have approached the vehicle A by passing each other, and stores the vehicle-to-vehicle communication information each time. The control unit 11 determines whether it is a predetermined timing for transmitting the vehicle-to-vehicle communication information to the vehicle management device 20 (step S103). The predetermined timing is the timing for each elapse of a predetermined period, the timing for accumulating a predetermined amount of inter-vehicle communication information, the timing for communicating with the roadside unit installed in the roadside zone and relaying the communication with the vehicle management device 20, and the timing. And so on. When it is time to transmit the stored vehicle-to-vehicle communication information to the vehicle management device 20, the control unit 11 instructs the second communication unit 13 to transmit the vehicle-to-vehicle communication information. The second communication unit 13 transmits the stored vehicle-to-vehicle communication information to the vehicle management device 20 using the second communication module 106 (step S104). A communication function (second communication unit) for transmitting and receiving information between the vehicle-to-vehicle communication function (first communication unit 12, first communication module 105) and the vehicle management device 20 for inter-vehicle communication with other vehicles. By separating the 13 and the second communication module 106), each communication control process can be simplified. In addition, communication control can be performed without the congestion of one communication affecting the other communication. Further, at the timing determined in step S103, the position information acquisition unit 14 acquires travel route information indicating each position traveled by itself from the RAM 103 and transmits it to the vehicle management device 20 using the second communication module 106 (step S105). ).

The control unit 11 determines whether the driving of the vehicle A is stopped (step S106). When the driving of the vehicle A is stopped, the process is stopped, and when it is not stopped, the process from step S101 is repeated.

The determination unit 23 determines the validity of the vehicle-to-vehicle communication information acquired from the in-vehicle device 10 by this determination.
The fare calculation unit 24 calculates the fare amount based on the traveling section in the fare section of the vehicle.

FIG. 6 is a diagram showing a processing flow of the vehicle management device according to the first embodiment.
Next, the processing of the vehicle management device 20 will be described step by step.
The reception information management unit 22 of the vehicle management device 20 receives vehicle-to-vehicle communication information and travel route information from each of the vehicle-mounted devices 10 of a plurality of different vehicles (step S201). The reception information management unit 22 records the received vehicle-to-vehicle communication information, the traveling route information, and the ID of the in-vehicle device 10 that has transmitted the information in association with each other in the database 30 (step S202). The vehicle management device 20 repeats the processes of steps S201 and S202 until a predetermined determination timing. The control unit 21 determines whether it is the determination timing (step S203). When the determination timing is reached, the control unit 21 instructs the determination unit 23 to start the determination process. The determination unit 23 identifies the ID of the first vehicle-mounted device 10 at the determination timing (step S204). The following description will proceed assuming that the ID of the vehicle-mounted device 10 specified here is the ID of the vehicle-mounted device 10A.

The identification of the ID of the in-vehicle device 10A may be performed based on the operation of the administrator, or information indicating the identification of some ID may be acquired from another device or the like. For example, the determination unit 23 may acquire the ID of the in-vehicle device 10A of the vehicle A for which the charge for the traveling section in the charge section is calculated from the higher-level device or the user, or based on the execution result of a predetermined program. You may get it. The determination unit 23 acquires the vehicle-to-vehicle communication information stored in the database 30 in association with the ID of the specified vehicle-mounted device 10A. The vehicle-to-vehicle communication information stored in the database 30 in association with the ID of the specified vehicle-mounted device 10A is referred to as the first vehicle-to-vehicle communication information.

The determination unit 23 extracts from the database 30 the first vehicle-to-vehicle communication information including the position information in the vicinity of the road position in the charging section from the first vehicle-to-vehicle communication information associated with the ID of the in-vehicle device 10A. (Step S205). As a result, the vehicle-to-vehicle communication information received from the in-vehicle device 10A at a position other than the billing section can be excluded from the information to be processed.

The determination unit 23 further extracts the vehicle-to-vehicle communication information received from the other vehicle-mounted device 10B including the ID of the vehicle-mounted device 10A identified in step S204 from the database 30. The vehicle-to-vehicle communication information received from another vehicle-mounted device 10B including the ID of the specified vehicle-mounted device 10 is referred to as a second vehicle-to-vehicle communication information. The determination unit 23 extracts from the database 30 the second vehicle-to-vehicle communication information including the position information near the road in the charging section from the second vehicle-to-vehicle communication information including the ID of the identified in-vehicle device 10A (step S206). ).

FIG. 7 is a diagram showing vehicle-to-vehicle communication information transmitted / received by the in-vehicle device in the billing section.
It is assumed that the vehicle A passes the four vehicles of the vehicle B1, the vehicle B2, the vehicle B3, and the vehicle B4 while traveling in the charge section. In this case, the vehicle-mounted device 10A of the vehicle A receives the inter-vehicle communication information B1-1 transmitted by the vehicle B1 when it passes by another vehicle B1. Further, the vehicle-mounted device 10A of the vehicle A passes the other vehicles B2, B3, and B4, so that the vehicle-mounted device 10B2 of the vehicle B2 receives the vehicle-to-vehicle communication information B2-1, and the vehicle-mounted devices 10B3 to B3-1 of the vehicle B3. Is received, and B4-1 is received from the in-vehicle device 10B4 of the vehicle B4. In step S205, these first vehicle-to-vehicle communication information B1-1, B2-1, B3-1, and B4-1 can be extracted. The timing at which the first vehicle-to-vehicle communication information B1-1, B2-1, B3-1, and B4-1 is received by the in-vehicle device 10A of the vehicle A is defined as T1, T2, T3, and T4. The order of timing is T1 <T2 <T3 <T4.

The vehicle-mounted device 10B1 of the other vehicle B1 receives the vehicle-to-vehicle communication information A-1 from the vehicle-mounted device 10A by passing the vehicle A. The vehicle-mounted device 10B2 of the other vehicle B2 receives the vehicle-to-vehicle communication information A-2 from the vehicle-mounted device 10A by passing the vehicle A. The vehicle-mounted device 10B3 of the other vehicle B3 receives the vehicle-to-vehicle communication information A-3 from the vehicle-mounted device 10A by passing the vehicle A. The vehicle-mounted device 10B4 of the other vehicle B4 receives the vehicle-to-vehicle communication information A-4 from the vehicle-mounted device 10A by passing the vehicle A. In step S206, these second vehicle-to-vehicle communication information A-1, A-2, A-3, and A-4 can be extracted. The timing at which the second vehicle-to-vehicle communication information A-1, A-2, A-3, and A-4 are received by the in-vehicle device 10 of each vehicle B1 to B4 is defined as T1, T2, T3, and T4.

The determination unit 23 of the vehicle management device 20 determines the first vehicle-to-vehicle communication based on the correspondence between the first vehicle-to-vehicle communication information extracted in step S205 and the second vehicle-to-vehicle communication information extracted in step S206. The validity of at least one of the information or the second vehicle-to-vehicle communication information is determined (step S207).

For example, the determination unit 23 extracts the vehicle ID from the first vehicle-to-vehicle communication information B1-1, B2-1, B3-1, and B4-1 extracted in step S205, and is based on the communication time included in each vehicle-to-vehicle communication information. Sort in ascending order. As a result, a permutation of vehicle IDs {B1, B2, B3, B4} is obtained. Further, the determination unit 23 extracts the vehicle ID recorded in the database 30 in association with the vehicle-to-vehicle communication information A-1, A-2, A-3, and A-4 extracted in step S206, and extracts each vehicle-to-vehicle distance. Sort in ascending order based on the communication time included in the communication information. As a result, a permutation of vehicle IDs {B1, B2, B3, B4} is obtained. The determination unit 23 of the vehicle management device 20 compares the permutations of the two vehicle IDs obtained, and if they match, extracts the first vehicle-to-vehicle communication information extracted in step S205 and the vehicle-to-vehicle communication information extracted in step S206. It is determined that the validity of each of the second vehicle-to-vehicle communication information is valid.

On the other hand, the determination unit 23 compares the permutations of the two vehicle IDs obtained, and if they do not match, the first vehicle-to-vehicle communication information extracted in step S205 and the second vehicle extracted in step S206. It is determined that the validity of any of the inter-vehicle communication information is invalid. For example, it is assumed that the determination unit 23 cannot extract the vehicle-to-vehicle communication information B3-1 and B4-1 to be received by the vehicle-mounted device 10A from the database 30 at the timings T3 and T4. In this case, the determination unit 23 obtains the permutation {B1, B2} of the vehicle ID. Further, the determination unit 23 extracts the vehicle ID recorded in the database 30 in association with the second vehicle-to-vehicle communication information A-1, A-2, A-3, and A-4 extracted in step S206. Sorting is performed in the order of earliest based on the communication time included in each vehicle-to-vehicle communication information, and a permutation of vehicle IDs {B1, B2, B3, B4} is obtained. In step S207, the determination unit 23 determines that the two permutations obtained are different. In this case, the validity of the first vehicle-to-vehicle communication information is invalid. For example, as an example, the vehicle IDs of B3 and B4, which should be obtained from the first vehicle-to-vehicle communication information, cannot be obtained from the first vehicle-to-vehicle communication information, so that the validity of the first vehicle-to-vehicle communication information is invalid. May be determined.

The determination unit 23 may determine the validity of the first vehicle-to-vehicle communication information or the second vehicle-to-vehicle communication information by another method or by further adding another method. For example, the determination unit 23 compares each position information included in the first inter-vehicle communication information with each position information included in the second inter-vehicle communication information. The determination unit 23 compares the position information included in the first vehicle-to-vehicle communication information with the position information included in the second vehicle-to-vehicle communication information at each timing. As a result of the comparison, when the determination unit 23 determines that the distance indicated by the two position information is separated by a predetermined distance or more at any timing, the first vehicle-to-vehicle communication information or the second vehicle-to-vehicle communication information It may be determined that the validity of at least one of the above is invalid.

The determination unit 23 may determine the validity of the first vehicle-to-vehicle communication information or the second vehicle-to-vehicle communication information by still another method or by adding the method. For example, the determination unit 23 compares the communication time included in the first vehicle-to-vehicle communication information with the communication time included in the second vehicle-to-vehicle communication information. When the communication time included in the first vehicle-to-vehicle communication information and the communication time included in the second vehicle-to-vehicle communication information differ by a predetermined time or more at each timing, the determination unit 23 determines the first vehicle-to-vehicle communication information. Alternatively, it is determined that the validity of at least one of the second vehicle-to-vehicle communication information is invalid. In this determination, the predetermined time used for determining that the timing of the communication time is different may be a time including the deviation time of the synchronization deviation of the time in each device. The validity of the vehicle-to-vehicle communication information can be defined as the fact that the correspondence between the first vehicle-to-vehicle communication information and the second vehicle-to-vehicle communication information is the same. If the correspondence between the first vehicle-to-vehicle communication information and the second vehicle-to-vehicle communication information is partially missing in one of the vehicle-to-vehicle communication information, the correspondence between the vehicles is missing. It may be possible to determine that the information is not valid. However, if the correspondence between the first vehicle-to-vehicle communication information and the second vehicle-to-vehicle communication information is partially missing in either one of the vehicle-to-vehicle communication information, the correspondence between the vehicles is missing. In some cases, it cannot be immediately determined that the communication information is not valid. For example, even if there is some omission in the correspondence between the first vehicle-to-vehicle communication information and the second vehicle-to-vehicle communication information for a short period of time, the first vehicle-to-vehicle communication information will be used for a long period of time thereafter. If there is a correspondence relationship between the second vehicle-to-vehicle communication information, it may be determined that any vehicle-to-vehicle communication information is valid.

When the validity of the vehicle-to-vehicle communication information is valid, the determination unit 23 acquires the travel route information received from the vehicle-mounted device 10A from the database 30 based on the vehicle-mounted device 10A having the ID specified in step S204. The toll calculation unit 24 identifies the position information corresponding to the charging section among the position information indicated by the traveling route information as the position information of the traveling section in which the vehicle A has traveled in the charging section (step S208). The determination unit 23 outputs the ID of the vehicle A and their position information to the charge calculation unit 24. The toll calculation unit 24 calculates the charge amount for the travel section based on the position information of the travel section in which the vehicle A has traveled within the charge section (step S209). The determination unit 23 determines whether the ID of the next in-vehicle device 10 that has not been processed can be specified (step S210). If the ID of the next in-vehicle device 10 that has not been processed can be specified, the determination unit 23 repeats the process from step S204. The determination unit 23 ends the process when the ID of the next in-vehicle device 10 that has not been processed cannot be specified.

When it is determined in step S207 that the validity of the vehicle-to-vehicle communication information is invalid, the determination unit 23 replaces the first vehicle-to-vehicle communication information extracted in step S205 with the second vehicle-to-vehicle communication information A-1, The position information included in A-2, A-3, and A-4 is specified as the traveled position information of the vehicle A between the position where the vehicle enters the charging section and the position where the vehicle A exits the charging section (step S211). That is, if the first vehicle-to-vehicle communication information may have been tampered with, or if it may not be accurate information, or the first vehicle-to-vehicle communication information could not be received by the vehicle management device 20. If possible, use the second vehicle-to-vehicle communication information for fare calculation. The determination unit 23 outputs the position information included in the second vehicle-to-vehicle communication information and the ID of the vehicle A included in the second vehicle-to-vehicle communication information to the charge calculation unit 24. The charge calculation unit 24 calculates the charge amount of the travel section within the charge section in which the vehicle A travels based on the ID and the position information of the vehicle A obtained from the determination unit 23 (step S212).

Although one embodiment of the present invention has been described above, according to the processing of the in-vehicle device 10 and the vehicle management device 20 described above, the reliability of the information of the traveling section in which the vehicle has traveled is enhanced, and the traveling in the predetermined charging section is performed. It is possible to calculate the billing amount with high accuracy according to the traveling of the section.

Further, according to the processing of the in-vehicle device 10 and the vehicle management device 20 described above, the traveling route of a specific vehicle is specified based on the inter-vehicle communication information obtained from the vehicles passing each other without providing the roadside unit in the charging section. Can be done.

The vehicle management device 20 may specify the traveling section of the specific vehicle based on the inter-vehicle communication information without detecting the traveling section of the specific vehicle in the charging section.

<Second embodiment>
The vehicle-mounted device 10A extracts position information from signals received from the other vehicle-mounted device 10B, and determines a position detection error of the GPS device 107 mounted on the vehicle A together based on the extracted position information. May be good.

FIG. 8 is a functional block diagram of the in-vehicle device according to the second embodiment.
The vehicle-mounted device 10 according to the second embodiment further includes the function of the position information determination unit 16 in addition to the functions described with reference to FIG.

FIG. 9 is a diagram showing a processing flow of the in-vehicle device according to the second embodiment.
Hereinafter, the processing of the in-vehicle device 10A provided in the vehicle A will be described. Similar to the first embodiment, the vehicle-mounted device 10 provided in the vehicle B is referred to as a vehicle-mounted device 10B. When the vehicle A passes the vehicle B after the vehicle-mounted device 10A is activated, the vehicle-mounted device 10B of the vehicle B enters the communication range of the vehicle-mounted device 10A. As a result, the first communication unit 12 of the vehicle-mounted device 10A transmits and receives a signal to and from the vehicle-mounted device 10B by vehicle-to-vehicle communication via the first communication module 105 (step S901). The signal transmitted by the first communication unit 12 to the vehicle-mounted device 10B by vehicle-to-vehicle communication includes at least the ID of the vehicle-mounted device 10A and the current position information of the vehicle A. The position information is the position information acquired by the position information acquisition unit 14 from the GPS device 107 provided in the vehicle A. Position information is information on coordinates on the ground such as latitude, longitude, and altitude. Similarly, the signal received by the first communication unit 12 of the vehicle-mounted device 10A from the vehicle-mounted device 10B also includes the ID of the vehicle-mounted device 10B and the position information of the vehicle B.

The first communication unit 12 of the in-vehicle device 10A stores the transmission information transmitted in step S901 in its own device (step S902). Further, the first communication unit 12 acquires the timed date and time of the time measuring unit 15 when the signal is received. This date and time information indicates the communication time. When the transmission / reception of the signal is completed by the vehicle-to-vehicle communication, the first communication unit 12 temporarily transmits the vehicle-to-vehicle communication information including the information included in the received signal and the communication time acquired from the timekeeping unit 15 at the time of receiving the signal. Store (step S903). That is, the first communication unit 12 stores the ID of the vehicle-mounted device 10B that communicates between vehicles in a storage unit such as the RAM 103, the position information of the vehicle B provided with the vehicle-mounted device 10B, and the communication time in association with each other.

The position information determination unit 16 acquires the transmitted transmission information and the vehicle-to-vehicle communication information generated based on the received signal from the other vehicle-mounted device 10B received at substantially the same timing as the transmission of the transmitted information. The position information determination unit 16 compares the position information included in the acquired transmission information with the position information included in the vehicle-to-vehicle communication information generated based on the corresponding received signal (step S904).

The position information determination unit 16 determines the position of either the own vehicle or another vehicle based on the position information included in the transmission information and the position information included in the vehicle-to-vehicle communication information generated based on the corresponding reception information. The validity of the information is determined (step S905). Specifically, the position information determination unit 16 compares the position information included in the transmission information with the position information included in the vehicle-to-vehicle communication information generated based on the reception information, and the distance between them is the same. If the distance is longer than a predetermined distance that can be determined to be present, it is determined that the GPS device mounted on the own vehicle or the GPS device mounted on another vehicle may be abnormal.

The position information determination unit 16 determines the distance between the position information included in the transmission information and the position information included in the vehicle-to-vehicle communication information generated based on the corresponding reception information for a predetermined number of times or more or for a predetermined time. If it is determined that the distance is equal to or greater than a predetermined distance, it may be determined that the GPS device mounted on the own vehicle is abnormal. Further, the position information determination unit 16 determines that the distance between the position information included in the transmission information only once and the position information included in the vehicle-to-vehicle communication information generated based on the reception information is equal to or greater than a predetermined distance. In that case, it may be determined that the GPS device provided in the other vehicle-mounted device 10B that has transmitted the received information is abnormal. When it is determined that the GPS device provided in the other vehicle-mounted device 10B is abnormal, the position information determination unit 16 immediately transmits a signal indicating that the position information is defective to the other vehicle-mounted device 10B that has transmitted the received information. It may be possible to notify that the measured position information is abnormal.

According to the above processing, the in-vehicle device 10 can determine an abnormality of the GPS device mounted on the own vehicle or the GPS device mounted on another vehicle by vehicle-to-vehicle communication.
